I see you did not read too closely here by I saying to change both plug
and
receptical which nobody including yourself said that. I know for a fact if
you
don't change both, you will come back to work on it again.

No, without actually seeing it in real life you certainly don't "know". It
may be a perfectly good plug on the end of that wire. The socket's grip on
it might also be perfect. It might be the connections made to the side of
the outlet. It might also be badly crimped or aluminum wires inside the
junction box. But without actually SEEING it you're just guessing. And a
guess when it's electrical is a BAD IDEA.
